I started out as a mathematician, but retrained
myself as a computer scientist. As a scientist, everyone wants their work
to have maximal impact, and sometimes that requires you to change the way
you think. My primary research
interests are in information retrieval, cryptology, network security,
parallel computing, and computational number
theory. (I was working on cryptography before it was cool, and I may still be
working on it afterwards).

I've had a web page for nearly a decade now, and it's less compelling than
it used to be. Nowadays people create blogs, but I manage to find other things
to do with my time. I still regard my scientific
publications (or here or here)
to be my most important publishing outlet because it has an
archival value and peer review (unlike the web). Some say that personal web
pages are passé now, but I disagree. Personal web pages are one of the
profound social changes that we are witnessing - the resurrection of the
political leaflet, the small business, and the individual. It's a remarkable
outlet for free speech, and can fundamentally change the social fabric of the
world.

I started a tongue-in-cheek criminal web site called DigiCrime, Incorporated as an educational
mechanism back in 1995, and it still generates some of the weirdest
email you could imagine. It's now out of date, but I don't have the heart
to kill it off. People sometimes remember a joke better than a technical
explanation. That's why I started SIGCRAP.
